Had more time to play around with this, and wanted to provide my updated thoughts. As some have stated, this mod may drive better than anything from the stock content. Specifically for me, the feeling at the limit is much more natural and progressive. No more exaggerated loss of traction when upshifting in a high-powered car. Much better behavior when sliding the rear in and out of corners. My only observation with regards to the driving experience is that the gearing could be a tad high. Should be able to dump the clutch in 1st, and swing the car around when trying to do a quick 180 (useful if you overcook it into an escape road).
Also the title specifically says "Road" there'll be an update with the oval chassis when we are done with it.
